Over-The-Air Device Firmware Upgrade (Alpha)#

Wi-SUN Over-The-Air Device Firmware Upgrade (OTA DFU) service is implemented for updating Wi-SUN device's firmware. The component uses the Gecko Bootloader API to perform firmware write, verify, and set to bootload operations.

A Trivial File Transfer Protocol (TFTP) client provides downloader solution to obtain a new Gecko Bootloader File (GBL) file from remote host Over-The-Air, using the Wi-SUN network. The connection to the TFTP remote host can be configured in component configuration file. The entire firmware upgrade session can be managed over CoAP. The service includes notification and status request capabilities.
